Fruit

Fruit anatomy is the internal structure of fruit, the mature ovary or ovaries from one or moreflowers. In fleshy fruits, the outer and often edible layer is the pericarp, which is the tissue that develops from the ovary wall of the flower and surrounds the seeds.

In some seemingly pericarp fruits, the edible portion is not derived from the ovary. For example, in the fruit of the ackee tree, the edible portion is an aril; and in the pineapple several tissues from the flower and stem are involved.

A cavity inside the fruit that contain the ovules or seeds                                                                                                    called a cell.

Parts of a Fruit

FRUIT PARTS

pericarp	the fruit wall (derived from the ovary of the pistil) which is composed of the exocarp, mesocarp and endocarp (the three layers are not always recognizable, ex. dry fruit)
endocarp	the innermost layer of the pericarp (often hard, stony or papery)
mesocarp	the middle layer of the pericarp (often fleshy)
exocarp	the outermost layer of the pericarp (often like a skin or peel). (peach)
